The pipeline runs asynchronously from the main thread and read always gets the most recent buffer. Often, it is convenient to read from the camera in a loop, as in the following code example. You can now read images from each camera in the pipeline and access them as numpy arrays. from jetmulticam import CameraPipelineĪnd that’s it-the pipeline has been initialized and started. In the following example, the elements correspond to device nodes /dev/video0, /dev/video1, and /dev/video2. Pass a list of cameras to include in the pipeline with the initializer argument. Basic multi-camera pipelineĪfter the setup, you can create a basic pipeline using the CameraPipeline class.

Then, install the jetmulticam package: $ git clone $ cd jetson-multicamera-pipelines The GMSL interface enables the flexibility to position cameras away from the Jetson module Getting started with Jetmulticamįirst, download and install the NVIDIA Jetpack SDK on your Jetson board.

Mount them orthogonally to one another for a total FOV of 270°, as shown in Figure 2.įigure 3. The IMX185 cameras each have a field of view of approximately 90°.

In this specific multi-camera setup, you use the following hardware: For more information about compatible cameras from NVIDIA partners, see the comprehensive list. There are many parameters to consider when choosing a camera: resolution, frame rate, optics, global/rolling shutter, interface, pixel size, and so on. The PeopleNet detections are used to perform person-following logic. Red Boxes correspond to DashCamNet detections, green ones to PeopleNet. Demo showing 3 independent cameras with ~270° field of view.

Finally, I add custom logic (person following) based on the DNN object detections to obtain the results shown in the following video: Video 1. I demonstrate a specific use case on a robot with a surround camera system. Specifically, I present jetmulticam, an easy-to-use Python package for creating multi-camera pipelines.

In this post, I showcase how to realize these common tasks efficiently on NVIDIA Jetson platform. Flow of the pipeline implemented in this project
